Patented Sept. 13, 1932 UNITED STATES PATENroFF'IcE JOHN LORNE BEATON, FPABKLAND, ALBERTA, CANADA, ASSIGNOR OF ONE-FOURTH TO GUSTAV ERNEST ANTONMALCHOW, OF STAVELY, CANADA GREASE GUN FILLER Application filed.November 5, 1930. Serial No. 493,539.

My invention relates to improvements in grease gun fillers, and theobject of the invention is to devise a simple, clean and inexpensivemeans whereby grease guns may be filled with grease preventing any dirtgetting into the grease either in the cans or with the grease as the gunis filled and alsopreventing the proper filling of the gun throughquantities of air passing into the gun with the grease, and it consistsessentially of the arrangement and construction of parts hereinaftermore particularly explained.

Fig. 1 is a perspective view of my filler partially broken away. toexhibit the construction thereof.

Fig. 2 is a longitudinal section through the filler and gun (on adiminutive scale).

Fig. 3 is an elevation of the grease gun on the same scale as Fig. 2.

In the drawings like letters of reference indicate corresponding partsin each figure.

1 is a base provided with base standards 2 and 3 upon which is supporteda cylinder 4 forming a grease chamber having a conical bottom 5. 6 is anopening in the apex of the conical bottom 5 from which extends a nipple7 which is normally provided with a closing cap 8 which is screwed on tothe end of the nipple. 9 is a circular cover for the open end of thegrease chamber to which is secured a locking bar 10 having concentricslots 12 and 13. 14 and 15 are reinforcing bars secured to the cylinder15 provided at one end with hooks 1O engaging the peripheral end of thecylinder 4 and provided attheir opposite end with threaded stems 16extending through the slots 12 and 13 when the parts are in the lookingposition.

17 are nuts which are screwed on to the stems 16 and bear against theouter face of the bar 10. The bars 15 be secured to the walls of thecylinder 4 if desired. The cylindrical top 9 is provided with a centralorifice 9 in which is secured afianged sleeve 18 by I means of a cotterpin 19 extending through the stem extension 20 of die sleeve U l 18. 21is a threaded spindle formed integral with the sleeve 18 and extendingaxially of the cylinder 4:.

22 is a disc provided withpa nut 23 formed integral therewith which isscrewed on to the spindle 21. 24'is a piston cup formed of leather orother suitable material secured to the disc 22. The stem extension 20 ispro-' vided with a diametric orifice 20 through which a handle 25extends. 26 is a grease gun of common construction, the cylindrical bodyof which is provided with a filling ori fice 26 from which extends anipple projection 27. The nippleprojection 27 is exteriorly threaded andnormally provided with a covering cap 28.

When it is desired to fill the gun all it is necessary to do is toremove the caps 8 and 28 and insert the nipple projection 27 into thenipple tube 7 in the position shown in Fig. 2.

The handle 25 is inserted'through the orifice 20 and the spindle 21rotated so as to .carry the piston cup 20 downward and force the greaseinto the interior of the gun through the filling orifice 26.

By this means it will be seen that the whole contents of a can may beinserted in my cylinder 4 and when the piston 24 is operated the greaseis forced therefrominto the gun without any possibility of any dirtcoming in contact therewith or any air entering the gun which willprevent the proper filling of the same, and also enable of the gun beingfilled of the piston for forcing the piston against the grease, aclosure for the open end ofthe cylinder, a cross bar secured to theclosure and projecting diametrically from each side thereof and havingconcentrically slotted end portions, and reinforcing bars having hooksat one end engaging one end of the cylindrical member, and threadedstems at the opposite end of such reinforcing bars extending through theaforesaid concentric slots, and nuts threaded upon the stems against thecross bar.
